This is something Docker does, and we did not do until now. Most difficult/annoying part was the REST API, where I did not really want to modify the struct being sent, so I made the new restart policy parameters query parameters instead. Testing was also a bit annoying, because testing restart policy always is. Signed-off-by: Matt Heon <mheon@redhat.com>
